Application filed February 23.190'1. Serial No. 359.023.

- To all whom it mayiconcem: Be it known that I, WVILLIAM GALLOWAY,

a citizen of the United States of America,

and a resident of Waterloo, Blackhawk manure'spreaders, and the object of my improvement is to provide means for adjusting the sprocket chains which drive the beater drum so that they may be used on the driving sprocket 'wheels affixed to the wagon wheels of'the spreader, suchadjustment be 'ing in the spacing apart to accommodate difl'erentrunning-gears of greater or less widths apart. his object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawing, in which- Figure 1 is a dplan viewof a manurespreader equippe with my improved adjustable spacing means, and Fig. 2 is aside elevation of the same.

My invention is devised to be incorporated in the mechanismof a detachable spreader arranged to be superposed upon the running gear of any ordinary wagon. the width between wagon wheels vary, it is necessary to devise some means for adjusting the spacing apart horizontally of the sprocket chains so that they may properly engage the driving sprocket wheels affixed to the inner sides of the rear driving wheels of the wagon. In the drawing I have shown a spreader box 18 supported upon therunning gear of an ordinary wagon. The rear wheels of the wagon 10 have the large driving sprocket Wheels 9 attached to their inner sides by meansof the bracket connections 17. The driving sprocket chains 8 which engage said sprocket wheels 9 also actuate the smaller forward sprocket wheels 15 and rear sprocket wheels 20. The hubs of the rear sprocket wheels 20-which are rotatab'ly mounted on the shaft 3 of the beater drum 16,'are provided with teeth 4 on their inner sides adapted to engage teeth on tho outcr faces of the collars 2. The collars 2 are mounted on the shaft 3 so as to slide thereon for adjustment but when properly adjusted to be secured to said shaft by means of sotscrews-1. Collars 6 are slidably mounted on the outer ends of the shaft3 and are provided Inasmuch as with set-screws 7 whereby they may be fixed inany position in which they are adjusted. Thehubs of the sprocket wheels 20 are horizontally slidable but their teeth 4 are ordinarily kept in engagement with the teeth on the collars 2 by means ofthe springs 5 interposed between said hubs and the collars 6. The forward sprocket wheels 15 are rotatably mounted on the outer portions of the short shafts 14, the inner ends of said shafts being affixed within vertically adjustable levers 12 pivoted to studs 28 on the box 18* by means of set-screws '11.

The short shafts. 14 are longitudinally slidablc within hearings in adjusted are aiiixed thereto by means of the set-screws 11.

The levers 12 are raised and lowered by means of the levers 26 whose rear ends are secured to a rock-shaft 27, the levers 12 being passed through loops on the forward ends of said levers 26. To a stud 23 on one side of the box 18 the lower end of a hand-lever 24 is fulcrumed, saidlever working in and adapted to engage a rack 25 for forward At a medial place on and back positions. the lever 24 is pivoted an interiorly threaded coupling 22 into which is adjustably screwed the threaded front end of a connecting-rod 21, whose rear end is pivoted to the forward end of one of the levers 26, and by which means the levers 26 are raised 'or lowered at will to causethe levers 12 to rise or fall and the sprocket-chains 8 to be in disengagement or engagement as the case may be with the driving sprocket-wheels 9.

When the'spr'eader box 18 has been placed upon the bolsters of the running gear of an ordinary wagon having front wheels 19 and rear wheels 10, in case the rear wheels 10 are more widely separated than usual the sprocket chains 8 may bendjusted to engage the sprocket wheels 1) attaclml to the whccls 10 in the following manner. T he set-screws 1 and 7 also the set-screws 11 are loosened and the collars 2 and 6 moved outwardly on the shaft 3, while the short shaft 14 is itself moved outwardly, all to a sufficient distance to permit of the sprocket chains is engaging the sprocket wheels 9. All of said setscrcws are then secured against said shafts leaving the mechanism in operative position. In case the spreader mechanism above described is placed upon the bolsters of the running gear of a wagon whose wheels are distance inwardly by spaced a lesser distance apart than the above, the sprocket chains 8 are moved a sufficient reversing the above process. By these means I have been enabled to secure operative engagement of the sprocket chains with the driving sprocket Wheels attached to the rear Wheels of any runm'ng gear however variously spaced apart.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. in a manure-spreader, the combination with a body supported on carrying-Wheels having driving-sprocket-wheels secured to their inner faces, of a shaft rotatably mounted transversely to said-body, a horizontallyadjustable sprocket-wheel secured to each end of said shaft, a horizontally-adjustabie idler-sprocket-Wheel rotatably mounted on a stub-shaft on each side of said body, a.

sprocket-diam on each side of said body passing about the idlerand the drivensprocket-wheel on the same side, each of said sprocket-chains being adapted to engage and be drivenby the driving-sprocket-vvheel on the same side. i

2. in a manure spreader, the combination with a body supported on carrying-Wheels,

of a beater-drum mountedon a shaft at one end of said body, horizontally-slidable sprocket-Wheels on saidshaft, means for adjusting and securing said sprocket-Wheels a desired distance apart,'s}5rocket-Wheels on the rear carrying-Wheels affixed thereto,

sprocket-chains engaging both the drivingand driven. -sprocket-wheels aforesaid, and means for ad usting theforward ends of said sprocket-chains to a desired distance apart.

3. in a manure spreader, the combination with a body supported on carrying-Wheels having driving-sprockets aflixed to their inner faces, of a vertically-adjustable idlersprocket-carrying lever pivoted on each side liof said body, a short shaft horizontallyslid able in a bearing in the free end of each lever, means for fixing each shaft inadesired posiin each lever, an idler-sproeket-wheel' rotatable on each shaft, driven sprocket-Wheels, a sprocket-chain on each side ofsaid-body passing ab out said idler and one of the driyensprocket-Wheels, and means for elevating or lowering said idler-carrying-l'evrs to disengage or engage said sprocket-chains from or with said driving-sprocket-whels.

4. In a manure spreader, the combination same side, a hand-lever pivoted to said body,

.or back position of adjustment, and a conbody; a v
